SELF-LOADING VEHICLE.

Application filed May 5, 1923. Serial No. 636,866.

To all whom it may concern: to dump its load into the body 4:, and back Be it known that I, GEORGE W. Or'rnusou. again. In the construction herein more a citizen of the United States, and a resispecifically contemplated the track is disdent of Seattle, in the county of King and posed at one side of the body.

To this rails 9 .and by suitable connecting members end the invention may be said to comprise 13. Additional, lateral rollers 14 on this the parts, improvements and combinations hoisting and' dumping track carriage are hereinafter described with reference to a engaged in a longitudinal channel 15 on the 35 preferred embodiment and set forth generioutside of the lower part of the side of the 7 cally and specifically in the claims. body, and. brace the carriage against lateral In the accompanying drawings, forming tilting displacement either outward'or ina part hereof: ward.

At the top driving shaft of the vehicle in advance of of the body side the rails are bent inward the transmission, or it may be a special shaft at an inclination carrying them well toward connected. with one of the power take-offs the center of the top of the body; and at which are familiar in commercial trucks, the this region the track rails are provided with arrangement in any event being such that inwardly projecting dumping spurs 1.8 which this shaft can be driven by the engine when diverge from the continuations 19 of the the vehicle is at rest. Such matters being rails, so that when the car is hoisted to this 4% well known, require no special illustration. part of the track the rollers 16 travel in the Mounted onthe chassis is a tiltable, rearspur projections 18 while the rollers 17 produmping cargo body 4, having a top hinged ceed along the continuations 19, causing the rear-gate 5 adapted to swing rearward.

In certain generic aspects of stretches along the lower portion 0 the side the invention this loader may be of different of the body 4:, and about pulleys or sprocket types. Specifically and preferably it com wheels 22 mounted on said side near the opprises a track 9'and a car 10 movable thereposite ends thereof. The upper stretch of on from a point near the ground upward this endless'member is secured to a clip 23 F111 on the forward onset the track rails 9, and the lower stretch is free. Thus, when the cable is operated in one direction by a crank handle 24 connected to the rear pulley, the loader is moved forward, and when the cable is operated in the other direction the loader is moved rearward. In any position the loader is locked and held by means comprising a dog 25 cooperative with a toothed wheel 26 mounted with the rear pulley.

The car 10 is hoisted and lowered by means or cables2? which pass upward from the sides of the car to rotatable drums 28 journaled in brackets 29 on the upper end of the hoisting and dumping track carriage and movable forward and rearward therewith. These drums are slidably splined on a longitudinal driven shaft 30 extending longitudinally over the top of the body and having suitable fixed suppoitupon the body 4 represented by an arm 31 of a forward gear bracket 32, whereby is held against longitudinal movement, theshaft being fixedly supported or not at the rear.

On the forward end of the shaft 30 is a gear 33, by which through suitable intermediate gears 34 it is driven from the upper end of a shaft 35 which extends vertically downward at the front of the body by which it is carried, the shaft being journaled in the bracket 32 referred to and in another bracket 36 on the lower portion of the body. The lower end of this shaft carries a friction cone clutch member 37.

The complementary, driving member 38 is on the upper end of a short vertical shaft 39 projecting upward from a gear-case 40 mounted in the chassis, this shaft being driven by the shaft 3 through suitable gears 41. This friction member is slidably splined I on its shaft, so as to be capable of yielding when the body 4, after having been tilted to dump, is lowered to its normal position bringing the member 37 down on the member 38, and is sustained by a spring 42 so as to produce a driving engagement. The cone clutch elements thus constitute embodiments of separable driving and driven elements carried by the chassis and tiltable body respectlvely whereby the loader can be driven whenthe body is down. They also afford a clutch for throwjngthe power on and 0d the loader at the proper times, a means for holding the car at the top in dumping ,position for the necessary briei period, and a means for efiecting controlled lowering oi the car. To these ends means are provided for shifting the clutch member 38 by the attendant, the said means being shown as comprising a yoke lever l -3 and a link 44, which will be understood as passing to a handle or pedal at a suitable point. When the car is brought up against the bumpers 20 the clutch automatically slips, so that injury is prevented and the power merely serves to shortens, and vice-versa.

as er.

The top of the body l is provided with a suitable cover 45 to restrain flying ashes or the like, this cover being arranged to leave a necessary opening along the side where the car discharges its material. In order to close this opening as much as may be, extensible and contractible closures are provided at opposite sides of the loader and connected thereto, so that when the loader is moved forward or rearward one closure automatically extends and the other These closures may talre the form, for example, of fiezri ble strips 46 substantially the width of the opening, adapted to be wound and unwound. upon spring shade rollers 47 mounted at the opposite ends of the body, the strips extending from these rollers toward the track male 9, to which their ends are secured.

The operation will be briefly summarized. The vehicle having reached a point of collection is brought to rest, and the car 10 is lowered to the bottom of the track 9. The engine is to be understood as running and rotating the shaft 3. The clutch member 38 is held out while the car is receiving its load, and then put into driving engagement with the complementary member 37. This causes the car to be hoisted to the top of the track and there upturned so that loo its contents fall into the body. The clutch ill? the operation is repeated. When one portion of the interior or the body becomes suficientlyfilled the loader is moved to a new point along the side of the vehicle, and this may be done several times so that the body becomes evenly filled from frontto rear. When the body hasbeen sufficiently loaded the vehicle is driven to the approprlate spot, the rear gate unlocked, and the body uptilted to dump. In this operation the drive for the hoist separates at the clutch members 37, 38, the clutch member 37 rising away from the member 38. Dn again lowering the. body the spring 42 cushions the contact of the members, preventing shock to the shafts and bearings. When the vehicle is traveling the loader forms no lllti tall to slip automatically when body, and mechanism ineaaai undue projection likely to cause trouble. liVhen the machine is traveling or the loader is not in use, the clutch is held out in an appropriate manner.

While the preferred embodiment of the invention has been described in detail, it will be understood that numerous other and specifically different embodiments are possible, and I do not therefore wish to limit myself to the precise construction illustrated.
